APPLIGATION FILED 00T.l2, 1906.

QLLQ 5 UNITED STATES PATENT OFFICE.

To all whom it may concern.-

Be it known that I, JAMES ALBERT LIGHT- BODY, a citizen of the UnitedStates, residing at Waterville, in the'county of Kennebec and State ofMaine, have invented new and useful Improvements in Brake Rigging, ofwhich the following is a specification.

My invention pertains to the brake-rigging cars and it contemplates theprovision of a brake-rigging designed with a view of assuring safety andof withstanding the rou h usage to which railway-brakes 'are-ordinari ysubjected.

The invention Will be fully understood from the following descriptionand claims when the same are read in connection With the accompanyingdrawings, forming part of this specification, in Which Figure l is avfront elevation illustrating the rigging constituting one embodiment ofmy invention as properly applied. Fig. 2 is a vertical sect-ion taken inthe lane indicated by the line 2 2 of Fig. 1 100 n in the directionindicated by the arrow. a plan view of the rigging, and Fig. 4 is anenlarged detail perspective view illustrating a portio n of thebrake-beam and my novel safety-loo p attached thereto.

Similar letters designate corresponding parts in all of the views of thedrawlngs, re-

erring to which A is a car-axle.

B B are the wheels carried by the axle.

C is a truck-bar having lower and upper flanges a and. b and also havingapertured In S 0.

I) 'is a brake-beam, of the form shown in construction or'of any othersuitable form compatible With the purpose of my invention, equipped Withbrake-shoes d. v

E are han ers through which the end portions of the cam D are connectedwith the ,lugs c of thetruck, and F is my novel bracket for assisting inthe suspension of the brake-beam D from the truck. The said bracket Fcomprises a top bar e, fixedly connected at f to the top flange 1) ofthe truck and extending at a-right angle thereto, and a brace-bar g,fixedly connected at k to the lower flange (1 of the truck-bar andextendin upward and outward from said flan e .an'

referabl though not necessarily, we ded at to the ar e. As thus formedthe bracket F obviously constitutes a firm support for the brake-beam,with which it is connected in the manner presently set forth. The

Specification of Letters Patent.- Application filed October 12, 1906.Serial No. 333.591.

' approved manner without involving Patented Jan. 29, 1907.

brake-beam D is preferably reinforced and strengthened through themedium of a bar t, extending at a right angle from its middle, and.inclined truss-bars u, j oined to the beam and said bar If, and with thebracket F through a chain '22, connected to an eye w on the bar t, and ahook an, engaged with said chain 'v and having a threaded shank engaginga threaded aperture in the welded portion of the bracket and equippedabove the bracket with a nut y. The strengthening bar 25' of thebrakebeam supports the brake-lever L, Which is ffulcrumed at z therein,and to the lower arm of said lever is connected the brake-connecting rodM, while the up er arm thereof serves for the connection of the chain orrod (notshownlto operate the brakes.

N is my novel safety-loop, which rests under the brake-connecting rod- Mand has for its office to catch and hold'or support the said rod in theevent of any of the connectingpins being displaced, thus assuring thesafetyof the car equipped with the brake. The brake-beam D'may, asbefore stated, be of any form in cross-section, and the safetyloop N maybe connected to said beam in apy eparture from the scope of myinvention. I prefer, however, to connect the safety-loop with the brakebeam' in the manner shownthatis, throu h the medium of a shackle a,-clasping and fixed on the brake-beam, and a bolt by which thesafety-loop is attached to said shackle.

P isa yoke carried by the brake-beam.

The upper' part of this'yoke serves, as illustrated, to support thelever L in its working position.

As-best shown in Fig. 1, the beam-hangers E are of loop form and areconnected with the apertured lugs c of the truck through the medium ofbolts R, secured in ter-pins S. In order to assist t e hangers E in thesuspension of the brake-beam D and form a rigging that will not shakeloose or ecome unfastened, I prefer to employ the safety-chains T,connected to the. brakebeam D through the medium of clevises U,

thebolts V of which pass throu h end links of the chains and serve tohold oth chains and clevises to the beam, and also connected to the topflange of the truck through the medium of e ebolts'W, checked by nuts X,the up er linlgs of the chains being preferably welde in the eyebolts.

place by cot- 1 ment of my invention;

'It will be gathered from the foregoin that my improvements contributemateri ly to the strength and durability of the brake-riggi and in thatway rol of t e same, and it wil also be gathered that the means providedfor meeting the contingency of the brake-connecting rod becominunfastened practically eliminates the lie ility of accident from thatcause.

The construction herein shown and de scribed constitutes the preferredembodibut I desire it understood that in practice such changes may bemade in the form, construction, and relative arrangement of parts asfairly fall within the scape of my invention as claimed.

-aving described my invention, What I claim, and desire to secure byLetters Patent, is- I 1. The combination in abrake-rigging, of atruck-bar, a bracket having upper and lower bars joined together andfixedly con nected to upper and lower portions, respecspectively,

t-ively, of the truck-bar, a brake-beam, and a connection intermediatethe bracket and the beam for hanging the latter from the former.

2.. The combination in a brake-rigging, of a truck-bar having upper andlower flanges, a bracket havingupper and lower bars welded together attheir outer ends and fixedly connected to the upper and lower flanges,re-

of the truckbar; said bracket having a vertically-disposed threadedaperture in the welded portions of its bars, a bolt having a threadedshank secured in said threaded aperture, a brake-beam, and a connec-tionintermediate said bolt and beam.

3. The combination in a brake-rigging, of a truck-bar having upper andlower flanges and also having lugs. adjacent to its ends, a brake-beam,hangers connecting said lugs and the end portions of the beam, a brackethaving upper and lowerbars welded together at'their outer ends andfixedly connected to the upper andlower flanges, respectively, of thetruck-bar; said bracket having a vertically-disposed threaded aperturein the welded portions of its bars, a bolt having a threadedshanksecu-red in said threaded aperture, and a connection between saidbolt and the intermediate portion of the brake-beam.

4. The combination in a brake-rigging, of a truck-bar having upper andlower flanges, a br'ake beam, a bracket having upper and lower barsjoined together at their outer ends and fixedly connected attheir innerends to the upper and lower flanges, respectively, of

ong the usefulness the truck-b ar, and a connection intermediate theouter portion of the bracket and the brake-beam.

5. The combination in a brake-rigging, of a brake-connecting rod, abrake-beam, and

means carried by the brake-beam for sup porting the brake-connectin rod.

6. The combination in a rake-rigging, of a brake-connecting rod, abrake-beam, and a safety-loop attached to the brake-beam and disposedunder the brake-connecting rod.

7. The combination in a brake-rigging, of a brake-connecting rod, abrake-beam, and a shackle fixed on the brake beam, and a safety-loopconnected to said shackle and disposed under the brake-connecting rod.

8..
